Alexey Samsonov b1c3991915 [TSan] Add a comment that tsan_flags.h may be included in the user code, and therefore shouldn't include other headers from TSan or common sanitizer runtime. User may need tsan_flags.h to provide its implementation of __tsan::OverrideFlags

llvm-svn: 158070
 2012-06-06 13:58:39 +00:00
Alexey Samsonov 51ae983718 [Sanitizer]: Introduce a common internal printf function. For now, also use tool-specific wrappers TsanPrintf (its output is controlled by TSan flags) and AsanPrintf (which copies its results to the ASan-private buffer). Supported formats: %[z]{d,u,x}, %s, %p. Re-write all format strings in TSan according to this format (this should have no effect on 64-bit platforms).
